EXECUTIVE SUMMARY
Scientific opportunity in optical/infrared astronomy is as high today as it has ever been. The physics of the expansion of the Universe is within our grasp, as are galaxy formation and evolution, star formation, and the evolution of planetary systems. NOAO’s responsibility is to manage the evolution of the O/IR observing system so that these opportunities can be realized in the climate of flat NSF budgets expected in the years 2005–2011. In this submission to the Division of Astronomical Sciences Review of Senior Facilities, we detail the scientific opportunities that can be realized if the path recommended in the recently-issued report of the O/IR Long-range Planning Committee is followed.1 We also describe the valuable science that would be lost if KPNO and CTIO were removed from NOAO’s existing system of facilities. In Section 5 of this document, we present a transition management plan for NOAO facilities that not only maximizes scientific opportunities, but also capitalizes on the investment of NSF resources already made in the NOAO program. NOAO proposes to divest 50% shares of the Mayall, Blanco, and 2.1 meter telescopes to operating partners in order to complete the re-distribution of resources to decadal survey initiatives shown in Figure 1. The national observatory will itself become a public-private partnership, with equal support from each sector for the 1–4 meter telescopes that are essential for effective use of the Gemini telescopes, their siblings in the U.S. system, and the emerging new generation of facilities. We make this proposal in support of the most recent decadal survey, Astronomy and Astrophysics in the New Millennium (AANM, 2001), in which the Astronomy and Astrophysics Survey Committee (AASC) envisioned revolutionary advances over the next ten to twenty years in our understanding of such fundamental questions as: how large-scale structure emerged from the density fluctuations imprinted during the Big Bang; how the first stars and galaxies were formed and how the simple galactic morphologies we observe today came to be; and how planetary systems form and evolve and how frequently planets amenable to life emerge. The optimism expressed in the AASC report derives primarily from the enormous progress already made over the past two decades, thanks to advances in detector technology and computational power, the launching of NASA’s Great Observatories, and the development of a suite of powerful new 8–10-m class ground-based telescopes. The authors of the decadal survey were confident that the pace of progress could be sustained, and indeed accelerated, via imaginative combinations of private and federal investment in critical next generation facilities. An “effective national observatory” was viewed as central to this vision. The AASC thus challenged NOAO to become that observatory, specifically recommending that NOAO:
(1) Work in partnership with the community and the private observatories to exploit the unique strength of the U.S. astronomical community—i.e., the large-scale private as well as public investment in major facilities—in order to achieve the design and construction of the next generation of ground-based telescopes.
(2) Take a leading role in shepherding the evolution of the complex “system” of U.S. public and private telescopes so that creative scientists throughout the U.S. community can continue to have access to the full range of facilities and capabilities required to carry out world-leading research.

NOAO enthusiastically embraced this challenge and beginning in 2001, undertook a rapid evolution from an observatory largely focused on operating and providing access to its own facilities (including U.S. access to the Gemini telescopes), to an institution that by 2005 had achieved such notable results as:
